You were obviously inspired by Dangerous Machine Type-6, and the fact that this isn't a Continuous Spell actually works its favor, so that the effects can be much more damaging. I like the fact that 3 of these effects damage the user (destroying or banishing the card, or take 500 damage), so that you have a 50% chance of getting no benefit from this card. That balances the effects beneficial to the player (destroy 1 card, banish 1 card on the field, opponent loses 1000).
I can't think of any way to improve this card. I like it, and I would probably play it.
